Microsoft’s Hypocrisy on AI

News Feed
Friday, September 13, 2024

Microsoft executives have been thinking lately about the end of the world. In a white paper published late last year, Brad Smith, the company’s vice chair and president, and Melanie Nakagawa, its chief sustainability officer, described a “planetary crisis” that AI could help solve. Imagine an AI-assisted tool that helps reduce food waste, to name one example from the document, or some future technology that could “expedite decarbonization” by using AI to invent new designs for green tech.But as Microsoft attempts to buoy its reputation as an AI leader in climate innovation, the company is also selling its AI to fossil-fuel companies. Hundreds of pages of internal documents I’ve obtained, plus interviews I’ve conducted over the past year with 15 current and former employees and executives, show that the tech giant has sought to market the technology to companies such as ExxonMobil and Chevron as a powerful tool for finding and developing new oil and gas reserves and maximizing their production—all while publicly committing to dramatically reduce emissions.Although tech companies have long done business with the fossil-fuel industry, Microsoft’s case is notable. It demonstrates how the AI boom contributes to one of the most pressing issues facing our planet today—despite the fact that the technology is often lauded for its supposed potential to improve our world, as when Sam Altman testified to Congress that it could address issues such as “climate change and curing cancer.” These deals also show how Microsoft can use the vagaries of AI to talk out of both sides of its mouth, courting the fossil-fuel industry while asserting its environmental bona fides. (Many of the documents I viewed have been submitted to the Securities and Exchange Commission as part of a whistleblower complaint alleging that the company has omitted from public disclosures “the serious climate and environmental harms caused by the technology it provides to the fossil fuel industry,” arguing that the information is of material and financial importance to investors. A Microsoft spokesperson said the company was unaware of the filing and had not been contacted by the SEC.)For years, Microsoft routinely promoted its work with companies such as Schlumberger, Chevron, Halliburton, ExxonMobil, Baker Hughes, and Shell. Around 2020, the same year Microsoft made ambitious climate commitments that included a goal to reach carbon negativity by 2030, the tech firm grew quieter about such partnerships and focused on messaging about the transition to net zero. Behind the scenes, Microsoft has continued to seek business from the fossil-fuel industry; documents related to its overall pitch strategy show that it has sought energy-industry business in part by marketing the abilities to optimize and automate drilling and to maximize oil and gas production. Over the past year, it has leaned into the generative-AI rush in an effort to clinch more deals—each of which can be worth more than hundreds of millions of dollars. Microsoft employees have noted that the oil and gas industries could represent a market opportunity of $35 billion to $75 billion annually, according to documents I viewed.Based on the documents, executives see these generative-AI tools—the buzziest new technology since the iPhone, and one that Microsoft has invested billions of dollars in—as a kind of secret weapon for client outreach. During an internal conference call with more than 200 employees last September, a Microsoft energy exec named Bilal Khursheed noted that, since the company’s generative-AI investments, the energy industry was turning to Microsoft for guidance on AI in a way that had perhaps “never happened before.” “We need to maximize this opportunity. We need to lay out the pathway to adopting generative AI,” he said, according to a transcript of the meeting I viewed. One such pathway? Using generative algorithms to model oil and gas reservoirs and maximize their extraction, Hema Prapoo, Microsoft’s global lead of oil and gas business, said later in the meeting. Several documents also emphasize Microsoft’s unique relationship with OpenAI as an additional selling point for energy clients, suggesting that GPT could drive productivity separate from fossil-fuel extraction. (OpenAI did not respond to a request for comment.)From a business perspective, of course, Microsoft’s pursuit of massive deals with fossil-fuel companies makes sense. And such partnerships do not necessarily mean that the company is contradicting its climate commitments. Microsoft executives have made the case that AI can also help fossil-fuel companies improve their environmental footprint. Indeed, both Microsoft and its energy customers defend their partnerships by arguing that their goals work in harmony, not contradiction. They told me that AI services can make oil and gas production more efficient, increasing production while reducing emissions—a refrain I saw repeated in documents as part of Microsoft’s sales pitches. In addition, some of these companies run wind farms and solar parks, which further benefit from Microsoft’s cloud technologies. Microsoft has also touted exploratory academic research into how AI could be used to discover new materials for reducing CO2 in the atmosphere.The idea that AI’s climate benefits will outpace its environmental costs is largely speculative, however, especially given that generative-AI tools are themselves tremendously resource-hungry. Within the next six years, the data centers required to develop and run the kinds of next-generation AI models that Microsoft is investing in may use more power than all of India. They will be cooled by millions upon millions of gallons of water. All the while, scientists agree, the world will get warmer, its climate more extreme.[Read: AI is taking water from the desert]Microsoft isn’t a company that exists to fight climate change, and it doesn’t have to assume responsibility for saving our planet. Yet the company is trying to convince the public that by investing in a technology that is also being used to enrich fossil-fuel companies, society will be better equipped to resolve the environmental crisis. Some of the company’s own employees described this idea to me as ridiculous. To these workers, Microsoft’s energy contracts demonstrate only the unsavory reality of how the company’s AI investments are actually used. Driving sustainability forward? Maybe. Digging up fossil fuels? As Prapoo put it in that September conference call, it’s a “game changer.”Before Holly Alpine left Microsoft earlier this year—fed up, she said, with the company’s continued support of fossil-fuel extraction—she had spent nearly a decade there working in roles focused on energy and the environment. Most recently, she headed a program within Microsoft’s cloud operations and innovation division that invests in environmental sustainability projects in the communities that host the company’s data centers. Alpine had also co-founded a sustainability interest group within the company seven years ago that thousands of employees now belong to. (Like the other named sources in this story, she did not provide any of the documents I reviewed.)Members of this group initially concerned themselves with modest corporate matters, such as getting the company’s dining halls to cut down on single-use items. But their ambitions grew, partly in response to Microsoft’s own climate commitments in 2020. These were made during a moment of heightened climate activism; millions around the world, including tech workers, had just rallied to protest the lack of coordinated action to cut back carbon emissions.Microsoft has failed to reduce its annual emissions each year since then. Its latest environmental report, released this May, shows a 29 percent increase in emissions since 2020—a change that has been driven in no small part by recent AI development, as the company explains in the report. “All of Microsoft’s public statements and publications paint a beautiful picture of the uses of AI for sustainability,” Alpine told me. “But this focus on the positives is hiding the whole story, which is much darker.”The root issue for Alpine and other advocates is Microsoft’s unflagging support of fossil-fuel extraction. In March 2021, for example, Microsoft expanded its partnership with Schlumberger, an oil-technology company, to develop and launch an AI-enhanced service on Microsoft’s Azure platform. Azure provides cloud computing to a variety of organizations, but this product was tailor-made for the oil and gas industries, to assist in the production of fossil fuels, among other uses. The hope, according to two internal presentations I viewed, was that it would help Microsoft capture business from many of the leading fossil-fuel providers. A spokesperson for Schlumberger declined to comment on this deal.Recent AI advances have complicated the picture, though they have not changed it. One slide deck from January 2022 that I obtained presented an analysis of how Microsoft’s tools could allow ExxonMobil to increase its annual revenue by $1.4 billion—$600 million of which would come from maximizing so-called sustainable production, or oil drilled using less energy. (An ExxonMobil representative declined to comment.) Other documents provided details on multiple deals Chevron has signed with Microsoft to access the tech giant’s AI platform and other cloud services. An executive strategy memo from June 2023 indicated that Microsoft hoped to pitch Chevron on adopting OpenAI’s GPT-3.5 and GPT-4 to “deliver more business value.” A Chevron spokesperson told me that the company uses AI in part to “identify efficiencies in exploration and recovery and help reduce our environmental footprint.” There is the tension. On the one hand, AI may be able to help reduce drilling’s toll on the environment. On the other hand, it’s used for drilling.[Read: Every time you post on Instagram, you’re turning on a light bulb forever]How do these companies weigh the environmental benefits of a more efficient drilling operation against the environmental harms of being able to drill more, faster? A Shell spokesperson provided a quantifiable example of their thinking: Microsoft’s Azure AI platform allowed Shell to calculate the best settings for its equipment, driving down carbon emissions at several of its natural-gas facilities. One facility saw an estimated reduction of 340,000 metric tons of carbon dioxide per year. This seems impressive: Using estimated emissions from the EPA, this is roughly the amount of CO2 generated by 74,000 cars annually. Relative to Shell’s total emissions, however, it’s practically insignificant. According to the company’s own reporting, Shell was responsible for about 1.2 billion metric tons of emissions last year.Within Microsoft, members of the sustainability group have repeatedly petitioned leadership to change its stance on these contracts. Google, for example, announced in 2020 that it would not make custom AI tools for fossil-fuel extraction—couldn’t Microsoft do the same? “We’ve never advocated for cutting ties with the fossil-fuel industry,” Alpine told me. Microsoft could work with clients on their transition to clean energy, without explicitly supporting extraction, Alpine reasoned.To help make her case, Alpine presented a memo to Smith in December 2021 that calculated the effects of the company’s oil and gas deals. She pointed, for example, to a single 2019 deal with ExxonMobil that could purportedly “expand production by as much as 50,000 oil-equivalent barrels a day by 2025,” according to a Microsoft press release. Those extra barrels would produce an estimated 6.4 million metric tons of emissions, drastically outweighing a carbon-removal pledge that Microsoft made in 2020, she wrote. (I verified her estimate with multiple independent carbon analysts. ExxonMobil declined to comment.)Employee advocates asked company leadership to amend its “Responsible AI” principles to address the environmental consequences of the technology. The group also recommended further restrictions on fossil-fuel-extraction projects. Around this time, Microsoft instead released a new set of principles governing the company’s engagements with oil and gas customers. It was co-authored by Darryl Willis, the corporate vice president of Microsoft’s energy division (and a former BP executive who served as BP’s de facto spokesperson during the Deepwater Horizon crisis). Unsurprisingly, it did not adopt all of the group’s suggestions.What it did include was a stipulation that Microsoft will support fossil-fuel extraction only for companies that have “publicly committed to net zero carbon targets.” This may be cold comfort for some: A 2023 report from the Net Zero Tracker, a collaboration between nonprofits and the University of Oxford, found that such commitments from fossil-fuel companies are “largely meaningless.” Most firms claim a net-zero target that fully accounts only for their operational emissions, such as whether their offices, car fleets, or equipment are powered with green energy, while ignoring much of the emissions from the fossil fuels they produce.When I talked with Willis about Microsoft’s energy business, he repeated over and over that “it’s complicated.” Willis explained that his team is focused on expanding energy access—“There are a billion people on the planet who don’t have access to energy,” he said—while also trying to accelerate the decarbonization of the world’s energy. I asked him how Microsoft planned to achieve the latter goal when it’s chasing contracts that help companies drill for fossil fuels. “Our plan, candidly stated, is to make sure we’re partnering with the right organizations who are leaning in and trying to accelerate and pull this [sustainability] journey forward,” he said. In other words, the company does not see its approach to selling the technology as incompatible with its sustainability goals. “AI will solve more problems than it creates,” Willis told me. “A lot of the dilemmas that we’re facing with energy will be resolved because of the relationship with generative AI.”Hoping to understand more about the company’s perspective, I also spoke with Alex Robart, a former Microsoft employee who left in 2022 and worked with Willis to write the energy principles. He called Microsoft’s approach practical. “Has Big Energy, incumbent energy, in a lot of ways behaved pretty badly, particularly in the past 25 to 40 years in the U.S. in particular, with regards to climate? Yeah, absolutely,” he told me. But he argued that fossil-fuel companies have to be part of the transition to cleaner alternatives and will do so only if they have financial incentives. “You need their balance sheets; you need their capital; you need their project-management expertise. We’re talking about building massive infrastructure, and building infrastructure is hard,” he said. Without that, “it’s fundamentally not going to work.”[Read: America’s new climate delusion]In the meantime, Microsoft has “not committed to a timeline” for phasing out work that is geared toward finding and developing new fossil-fuel reserves, a spokesperson said.Lucas Joppa, Microsoft’s first chief environmental officer, who left the company in 2022, fears that the world will not be able to reverse the current trajectory of AI development even if the technology is shown to have a net-negative impact on sustainability. Companies are designing specialized chips and data centers just for advanced generative-AI models. Microsoft is reportedly planning a $100 billion supercomputer to support the next generations of OpenAI’s technologies; it could require as much energy annually as 4 million American homes. Abandoning all of this would be like the U.S. outlawing cars after designing its entire highway system around them.Therein lies the crux of the problem: In this new generative-AI paradigm, uncertainty reigns over certainty, speculation dominates reality, science defers to faith. The hype around generative AI is accelerating fossil-fuel extraction while the technology consumes unprecedented amounts of energy. As Joppa told me: “This must be the most money we’ve ever spent in the least amount of time on something we fundamentally don’t understand.”

Can artificial intelligence really enrich fossil-fuel companies and fight climate change at the same time? The tech giant says yes.

Contributor: The left's climate panic is finally calming down

Millions of Americans may still believe warming exists, but far fewer view it as an imminent existential threat.

Is the American left finally waking up from its decades-long climate catastrophism stupor? For years, climate alarmism has reigned as political catechism: The planet is burning and only drastic action — deindustrialization, draconian regulation, even ceasing childbearing — could forestall certain apocalypse. Now, at least some signs are emerging that both the broader public and leading liberal voices may be recoiling from the doom and gloom.First, recent polling shows that the intensity of climate dread is weakening. According to a July report from the Yale Program on Climate Change Communication, while a majority (69%) of Americans still say global warming is happening, only 60% say it’s “mostly human-caused”; 28% attribute it mostly to natural environmental changes. A similar October study from the University of Chicago’s Energy Policy Institute found that “belief in human-driven climate change declined overall” since 2017. Interestingly, Democrats and political independents, not Republicans, were primarily responsible for the decline.Moreover, public willingness to countenance personal sacrifice in the name of saving the planet seems to be plummeting: An October 2024 poll from the Pew Research Center found that only 45% said human activity contributed “a great deal” to climate change. An additional 29% said it contributed “some” — while a quarter said human influence was minimal or nonexistent.The moral panic is slowly evaporating. Millions of Americans may still believe warming exists, but far fewer view it as an imminent existential threat — let alone embrace sweeping upheavals in energy policy and personal lifestyle.The fading consensus among ordinary Americans matches a more dramatic signal from ruling-class elites. On Oct. 28, no less an erstwhile ardent climate change evangelist than Bill Gates published a remarkable blog post addressing climate leaders at the then-upcoming COP30 summit. Gates unloaded a blistering critique of what he called “the doomsday view of climate change,” which he said is simply “wrong.” While acknowledging the serious risks for the poorest countries, Gates insisted that humanity will continue to “live and thrive in most places on Earth for the foreseeable future.” He added that “using more energy is a good thing, because it’s so closely correlated with economic growth.” One might be forgiven for suffering a bit of whiplash.The unraveling of climate catastrophism got another jolt recently with the formal retraction of a high-profile 2024 study published in the journal Nature. That study — which had predicted a calamitous 62% decline in global economic output by 2100 if carbon emissions were not sufficiently reduced — was widely cited by transnational bodies and progressive political activists alike as justification for the pursuit of aggressive decarbonization. But the authors withdrew the paper after peer reviewers discovered that flawed data had skewed the result. Without that data, the projected decline in output collapses to around 23%. Oops.The climate alarm machine — powered by the twin engines of moral panic and groupthink homogeneity — is sputtering. When the public grows skeptical, when billionaire techno-philanthropists question the prevailing consensus and when supposedly mainstream scientific projections reverse course, that’s a sign that the days of Al Gore’s “An Inconvenient Truth” propaganda documentary and John Kerry’s “special presidential envoy for climate” globe-trotting vanity gig are officially over.Ultimately, no one stands to benefit more from this incipient trend toward climate sanity than the American people themselves. In an era when optimism can be hard to come by, the professed certitude of imminent environmental apocalypse is pretty much the least helpful thing imaginable. If one is seeking to plant the seeds of hope, nothing could be worse than lecturing to the masses that one is a climate change-“denying” misanthrope if he has the temerity to take his family on an airplane for a nice vacation or — egad! — entertain thoughts of having more children. Even more to the point, given the overwhelming evidence that Americans are now primarily concerned about affordability and the cost of living, more — not less — hydrocarbon extraction has never been more necessary.There are green shoots that liberals and elites may be slowly — perhaps grudgingly — giving up on the climate catastrophism hoax to which they have long stubbornly clung. In America’s gladiatorial two-party system, that could well deprive Republicans of a winning political issue with which to batter out-of-touch, climate-change-besotted Democrats. But for the sake of good governance, sound public policy and the prosperity of the median American citizen, it would be the best thing to happen in a decade.Josh Hammer’s latest book is “Israel and Civilization: The Fate of the Jewish Nation and the Destiny of the West.” This article was produced in collaboration with Creators Syndicate.

The author highlights prominent figures like Bill Gates questioning the “doomsday view of climate change” and emphasizing that humanity will continue to thrive, arguing that increased energy consumption correlates with economic growth. The retraction of a 2024 Nature study that had predicted a 62% decline in global economic output by 2100—which peer reviewers found used flawed data—serves as evidence, according to the author, that catastrophic projections lack credibility. The author maintains that climate alarmism has been counterproductive to American well-being, fostering pessimism about the future and discouraging people from having children or pursuing economic development, and that moving away from this narrative will allow policymakers to address concerns Americans prioritize, particularly affordability and cost of living, through expanded hydrocarbon extraction.Different views on the topicScientific researchers have documented substantive health consequences from climate-related extreme events that suggest legitimate grounds for public concern rather than baseless alarmism. A comprehensive peer-reviewed literature review identified extensive evidence linking climate change to measurable increases in anxiety, depression, post-traumatic stress disorder, and suicidal ideation following extreme weather events such as heat waves, floods, hurricanes, and droughts[1]. The research demonstrates that approximately 80% of the global population experiences water and food insecurity resulting from climate impacts, with particularly acute effects in rural areas facing drought and agricultural disruption[1]. Scientific studies indicate that anthropogenic warming has contributed to increased frequency and intensity of extreme weather events, with vulnerable populations—including elderly individuals, low-income communities, women, and disabled persons—facing disproportionate risks due to limited access to resources and protection[1]. Rather than representing unfounded catastrophism, documented mental and physical health outcomes following extreme weather suggest that public concern about climate impacts reflects genuine public health challenges warranting policy attention and resource allocation for adaptation and mitigation strategies.

South Australia’s transport department misled the public by running ads on buses claiming “natural gas” was “clean and green”, the advertising regulator has found.The SA Department for Transport and Infrastructure has agreed to remove the advertising that has been on some Adelaide Metro buses since the early 2000s after Ad Standards upheld a complaint from the not-for-profit organisation Comms Declare.The ads have appeared on the side of buses that run on “compressed natural gas”, or CNG. In its complaint, Comms Declare said describing gas as clean and green was false and misleading as it suggested the fuel had a neutral or positive impact on the environment and was less harmful than alternatives.It said in reality gas was mostly composed of methane, a short-lived but potent fossil fuel.The Ad Standards panel agreed the ads breached three sections of its environmental claims code.It said CNG buses were originally introduced to provide more environmentally responsible transport than diesel buses, but transport solutions had evolved dramatically over the past 20 years and now included cleaner electric, hydrogen and hybrid alternatives.Comms Declare said multiple studies from across the globe had found buses that ran on CNG resulted in a roughly similar amount of greenhouse gas emissions being released into the atmosphere as buses that ran on diesel. It highlighted Adelaide Metro was now replacing its bus fleet with electric vehicles that it described as “better for the environment”.skip past newsletter promotionSign up to Clear Air AustraliaAdam Morton brings you incisive analysis about the politics and impact of the climate crisisPrivacy Notice: Newsletters may contain information about charities, online ads, and content funded by outside parties.

She said it followed similar rulings against Hancock Prospecting and Australian Gas Networks ads.“Methane gas creates toxic pollution at all stages of its production and use and is a major cause of global heating,” Noble said.Ad Standards said the Department for Transport and Infrastructure had “reviewed the decision and will take the appropriate action to remedy the issue in the near future”.A department spokesperson said it had received a direction from the Ad Standards panel to remove messaging from “a small number” of Adelaide Metro buses.The spokesperson argued that CNG was a “cleaner burning alternative to diesel” when it was purchased, offering about a 13% cut in greenhouse gas emissions and a “considerable reduction in harmful emissions” of carbon monoxide, nitrous oxide and particulates.

What’s the best way to expand the US electricity grid?

A study by MIT researchers illuminates choices about reliability, cost, and emissions.

Growing energy demand means the U.S. will almost certainly have to expand its electricity grid in coming years. What’s the best way to do this? A new study by MIT researchers examines legislation introduced in Congress and identifies relative tradeoffs involving reliability, cost, and emissions, depending on the proposed approach.The researchers evaluated two policy approaches to expanding the U.S. electricity grid: One would concentrate on regions with more renewable energy sources, and the other would create more interconnections across the country. For instance, some of the best untapped wind-power resources in the U.S. lie in the center of the country, so one type of grid expansion would situate relatively more grid infrastructure in those regions. Alternatively, the other scenario involves building more infrastructure everywhere in roughly equal measure, which the researchers call the “prescriptive” approach. How does each pencil out?After extensive modeling, the researchers found that a grid expansion could make improvements on all fronts, with each approach offering different advantages. A more geographically unbalanced grid buildout would be 1.13 percent less expensive, and would reduce carbon emissions by 3.65 percent compared to the prescriptive approach. And yet, the prescriptive approach, with more national interconnection, would significantly reduce power outages due to extreme weather, among other things.“There’s a tradeoff between the two things that are most on policymakers’ minds: cost and reliability,” says Christopher Knittel, an economist at the MIT Sloan School of Management, who helped direct the research. “This study makes it more clear that the more prescriptive approach ends up being better in the face of extreme weather and outages.”The paper, “Implications of Policy-Driven Transmission Expansion on Costs, Emissions and Reliability in the United States,” is published today in Nature Energy.The authors are Juan Ramon L. Senga, a postdoc in the MIT Center for Energy and Environmental Policy Research; Audun Botterud, a principal research scientist in the MIT Laboratory for Information and Decision Systems; John E. Parson, the deputy director for research at MIT’s Center for Energy and Environmental Policy Research; Drew Story, the managing director at MIT’s Policy Lab; and Knittel, who is the George P. Schultz Professor at MIT Sloan, and associate dean for climate and sustainability at MIT.The new study is a product of the MIT Climate Policy Center, housed within MIT Sloan and committed to bipartisan research on energy issues. The center is also part of the Climate Project at MIT, founded in 2024 as a high-level Institute effort to develop practical climate solutions.In this case, the project was developed from work the researchers did with federal lawmakers who have introduced legislation aimed at bolstering and expanding the U.S. electric grid. One of these bills, the BIG WIRES Act, co-sponsored by Sen. John Hickenlooper of Colorado and Rep. Scott Peters of California, would require each transmission region in the U.S. to be able to send at least 30 percent of its peak load to other regions by 2035.That would represent a substantial change for a national transmission scenario where grids have largely been developed regionally, without an enormous amount of national oversight.“The U.S. grid is aging and it needs an upgrade,” Senga says. “Implementing these kinds of policies is an important step for us to get to that future where we improve the grid, lower costs, lower emissions, and improve reliability. Some progress is better than none, and in this case, it would be important.”To conduct the study, the researchers looked at how policies like the BIG WIRES Act would affect energy distribution. The scholars used a model of energy generation developed at the MIT Energy Initiative — the model is called “Gen X” — and examined the changes proposed by the legislation.With a 30 percent level of interregional connectivity, the study estimates, the number of outages due to extreme cold would drop by 39 percent, for instance, a substantial increase in reliability. That would help avoid scenarios such as the one Texas experienced in 2021, when winter storms damaged distribution capacity.“Reliability is what we find to be most salient to policymakers,” Senga says.On the other hand, as the paper details, a future grid that is “optimized” with more transmission capacity near geographic spots of new energy generation would be less expensive.“On the cost side, this kind of optimized system looks better,” Senga says.A more geographically imbalanced grid would also have a greater impact on reducing emissions. Globally, the levelized cost of wind and solar dropped by 89 percent and 69 percent, respectively, from 2010 to 2022, meaning that incorporating less-expensive renewables into the grid would help with both cost and emissions.“On the emissions side, a priori it’s not clear the optimized system would do better, but it does,” Knittel says. “That’s probably tied to cost, in the sense that it’s building more transmission links to where the good, cheap renewable resources are, because they’re cheap. Emissions fall when you let the optimizing action take place.”To be sure, these two differing approaches to grid expansion are not the only paths forward. The study also examines a hybrid approach, which involves both national interconnectivity requirements and local buildouts based around new power sources on top of that. Still, the model does show that there may be some tradeoffs lawmakers will want to consider when developing and considering future grid legislation.“You can find a balance between these factors, where you’re still going to still have an increase in reliability while also getting the cost and emission reductions,” Senga observes.For his part, Knittel emphasizes that working with legislation as the basis for academic studies, while not generally common, can be productive for everyone involved. Scholars get to apply their research tools and models to real-world scenarios, and policymakers get a sophisticated evaluation of how their proposals would work.“Compared to the typical academic path to publication, this is different, but at the Climate Policy Center, we’re already doing this kind of research,” Knittel says. 

UK farmers lose £800m after heat and drought cause one of worst harvests on record

Many now concerned about ability to make living in fast-changing climate after one of worst grain harvests recordedRecord heat and drought cost Britain’s arable farmers more than £800m in lost production in 2025 in one of the worst harvests recorded, analysis has estimated.Three of the five worst harvests on record have now occurred since 2020, leaving some farmers asking whether the growing impacts of the climate crisis are making it too financially risky to sow their crops.

Record heat and drought cost Britain’s arable farmers more than £800m in lost production in 2025 in one of the worst harvests recorded, analysis has estimated.Three of the five worst harvests on record have now occurred since 2020, leaving some farmers asking whether the growing impacts of the climate crisis are making it too financially risky to sow their crops. Farmers are already facing heavy financial pressure as the costs of fertilisers and other inputs have risen faster than prices.This year Britain had the hottest and driest spring on record, and the hottest summer, with drought conditions widespread. As a result, the production of the five staple arable crops – wheat, oats, spring and winter barley, and oilseed rape – fell by 20% compared with the 10-year average, according to the analysis by the Energy and Climate Intelligence Unit (ECIU). The harvest in England was the second-worst in records going back to 1984.Supercharged by global heating, extreme rainfall in the winters of 2019-20 and 2023-24 also led to very poor harvests, as farmers were unable to access waterlogged and flooded fields to drill their crops.“This has been another torrid year for many farmers in the UK, with the pendulum swinging from too wet to too hot and dry,” said Tom Lancaster at the ECIU. “British farmers have once again been left counting the costs of climate change, with four-fifths now concerned about their ability to make a living due to the fast-changing climate.”He added: “There is an urgent need to ensure farmers are better supported to adapt to these climate shocks and build their resilience as the bedrock of our food security. In this context, the delays [by ministers] to the relaunch of vital green farming schemes are the last thing the industry needs.” The sustainable farming incentive was closed in March.Many farmers are struggling to break even and some blame environmental policies, but Lancaster said: “The evidence suggests that climate impacts are what’s actually driving issues of profitability, certainly in the arable sector, as opposed to policy change. Without reaching net zero emission there is no way to limit the impacts making food production in the UK ever more difficult.”David Lord, an arable farmer from Essex, said: “As a farmer, I’m used to taking the rough with the smooth, but recent years have seen near constant extreme rainfall, heat and drought. It’s getting to the point with climate change where I can’t take the risk of investing in a new crop of wheat or barley because the return on that investment is just so uncertain.“Green farming schemes are a vital lifeline for me, helping build my resilience to these shocks whilst providing cashflow to help buffer me financially.”Green farming approaches include planting winter cover crops. These increase resilience by boosting the organic content of soil, meaning it can retain water better during droughts. Cover crops can also help break up compacted soil, allowing it to drain better during wet periods.The ECIU analysis used production data for England published in October and current grain prices and then extrapolated it to the UK as a whole, a method shown to be reliable in previous years. Since 2020, which was the worst harvest on record, lost revenue associated with the impact of extreme weather is now more than £2bn for UK arable farmers. Grain prices are set globally, so low harvests in the UK do not translate in the market to higher prices.The link between worsening extreme weather and global heating is increasingly clear. The Met Office said the UK summer of 2025 was the hottest in more than a century of records and was made 70 times more probable because of the climate crisis. Global heating also made the severe rainfall in the winter storms of 2023-24 about 20% heavier.“This year’s harvest was extremely challenging,” said Jamie Burrows, the chair of the National Farmers’ Union combinable crops board. “Growing crops in the UK isn’t easy due to the unpredictable weather we are seeing more of. Funding is needed for climate adaptation and resilient crop varieties to safeguard our ability to feed the nation.”The price of some foods hit by extreme weather are rising more than four times faster than others in the average shop, the ECIU reported in October. It found the price of butter, beef, milk, coffee and chocolate had risen by an average of 15.6% over the year, compared with 2.8% for other food and drink.Drought in the UK led to poor grass growth, hitting butter and beef production, while extreme heat and rain in west Africa pushed up cocoa prices and droughts in Brazil and Vietnam led to a surge in coffee prices.A spokesperson for the Department of Environment, Food and Rural Affairs said farmers were stewards of the nation’s food security. “We know there are challenges in the sector and weather extremes have affected harvests,” she said. “We are backing our farmers in the face of a changing climate with the largest nature-friendly farming budget in history to grow their businesses and get more British food on our plates.”

Realtors just forced Zillow to hide a key piece of information about buying a home. Here’s why

Until recently, when you looked at a house for sale on Zillow, you could see property-specific scores for the risk of flooding, wildfires, wind from storms and hurricanes, extreme heat, and air quality. The numbers came from First Street, a nonprofit that uses peer-reviewed methodologies to calculate “climate risk.” But Zillow recently removed those scores after pressure from CRMLS, one of the large real-estate listing services that supplies its data. “The reality is these models have been around for over five years,” says Matthew Eby, CEO of First Street, which also provides its data to sites like Realtor.com and Redfin. (Zillow started displaying the information in 2024, but Realtor.com incorporated First Street’s “Flood Scores” in 2020.) “And what’s happened is the market’s gotten very tight. And now they’re looking for ways to try and make it easier to sell homes at the expense of homebuyers.” The California Regional MLS, like others across the country, controls the database that feeds real estate listings to sites like Zillow. The organization said in a statement to the New York Times that it was “suspicious” after seeing predictions of high flood risk in areas that hadn’t flooded in the past. When Fast Company asked for an example of a location, they pointed to a neighborhood in Huntington Beach—but that area actually just flooded last week. In a statement, First Street said that it stands behind the accuracy of its scores. “Our models are built on transparent, peer-reviewed science and are continuously validated against real-world outcomes. In the CRMLS coverage area, during the Los Angeles wildfires, our maps identified over 90% of the homes that ultimately burned as being at severe or extreme risk—our highest risk rating—and 100% as having some level of risk, significantly outperforming CalFire’s official state hazard maps. So when claims are made that our models are inaccurate, we ask for evidence. To date, all the empirical validation shows our science is working as designed and providing better risk insight than the tools the industry has relied on historically.” Zillow’s trust in the data has not changed, and that data is important to consumers: In one survey, it saw that more than 80% of buyers considered the data when shopping for a house. But the company said in a statement that it updated its “climate risk product experience to adhere to varying MLS requirements.” It’s not clear exactly what happened: In response to questions for this story, CRMLS now says it only asked Zillow to remove “predictive numbers” and flood map layers on listings, while Zillow says the MLS board voted to demand they block all of the data. It’s also not clear what would have happened if Zillow hadn’t made any changes, though in theory, the MLS could have stopped giving the site access to its listings. Images of Zillow’s climate risk tools from a 2024 press release [Image: Zillow] Zillow still links to First Street’s website in each listing, so homebuyers can access the information, but it’s less easy to find. The site also still includes a map that consumers can use to view overall neighborhood risk, if they take the extra step to click on checkboxes for flooding, fire, or other hazards. But the main scores are gone. Obviously, seeing that a particular house has a high flood risk or fire risk can hurt sales. Nevertheless, after First Street first launched, the National Association of Realtors put out guidance saying that the information was useful—and that since realtors aren’t experts in things like flood risk, they shouldn’t try to tell buyers themselves that a particular house is safe, even if it hasn’t flooded in the past. First Street’s flood data goes further than that of the Federal Emergency Management Agency, which uses outdated flood maps. It also incorporates more climate predictions, along with the risk of flooding from heavy rainfall and surface runoff, not just flooding from rivers or the coast. And it includes predictions of small amounts of flooding (for example, whether an inch of water is likely to reach the property). Buyers can dig deeper to figure out how much that amount of flooding might affect a particular house. It’s not surprising that some high risk scores have upset home sellers who haven’t experienced flooding or other problems in the past. But as the climate changes, past experiences don’t guarantee what a property will be like for the next 30 years. Take the example of North Carolina, where some residents hadn’t ever experienced flooding until Hurricane Helene dumped unprecedented rainfall on their neighborhoods. Redfin, another site that uses the data, plans to continue providing it, though sellers have the option to ask for it to be removed from a particular home if they believe it’s inaccurate. (First Street also allows homeowners to ask for their data to be revised if there’s a problem, and then reviews the accuracy.) “Redfin will continue to provide the best-possible estimates of the risks of fires, floods, and storms,” Redfin chief economist Daryl Fairweather said in a statement. “Homebuyers want to know, because losing a home in a catastrophe is heartbreaking, and insuring against these risks is getting more and more expensive.” Realtor.com is working with CRMLS and data providers to look into the issues raised by the MLS over the scores. “We aim to balance transparency about the evolving environmental risks to what is often a family’s biggest investment, with an understanding that the available data can sometimes be limited,” the company said in a statement. “For this reason we always encourage consumers to consult a local real estate professional for guidance or to learn more. When issues are raised, we work with our data partners to review them and make updates when appropriate.” If more real estate sites take down the scores, it’s likely that some buyers won’t see the information at all. First Street says that while it’s good that Zillow still includes a link to its site, the impact is real. “Whenever you add friction into something, it just is used less,” Eby says. “And so not having that information at the tip of your fingers is definitely going to have an impact on the millions of people that go to Zillow every day to see it.”
